Add voice and sound detection to your smart home hub. The MIC ADD-ON is a tiny digital microphone module that captures high-quality 24-bit audio and sends it directly to your device — no extra sound cards or converters needed. It's designed for hands-free voice commands, sound-triggered automations (like detecting a doorbell, glass break, or baby crying), and ambient noise monitoring. The microphone draws under 0.5 mA, so it has virtually no impact on battery life or power consumption. Its compact size means it fits inside the device housing without adding bulk.
